Hi, I'm trying to use Cory1492's ETool 3.13 to backup my save for Mario Kart (U) and use it with EZ4. I put the ETool3.gba on my mini-SD and ETool3.sav on my saver folder on mini-SD, then I loaded it in NDS mode on my DS. I selected backup EEPROM to SRAM and it said completed. Then I restarted my DS to let EZ4 write the SRAM into ETool3.sav. But when I tried to decompress ETool3.sav on my computer using the included ETxtract.exe, it gives me error message and I'm forced to close the program when it's at "Deflate buffer overflow.". Can anyone help me?
